WCF 动态调用(1)
很多时候,服务地址都不止一个的,这个时候就要动态去配置地址。配置Web.config,很麻烦
下面就看看怎样实现动态调用WCF。
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ServiceModel; using System.ServiceModel.Channels; /// <summary> /// 动态调用WCF的工具类库 /// </summary> public class InvokeContext { #region Wcf服务工厂 public static T CreateWCFServiceByURL<T>(string url) { return CreateWCFServiceByURL<T>(url, "wsHttpBinding"); } public static T CreateWCFServiceByURL<T>(string url, string bing) { if (string.IsNullOrEmpty(url)) throw new NotSupportedException("this url isn`t Null or Empty!"); EndpointAddress address = new EndpointAddress(url); Binding binding = CreateBinding(bing); ChannelFactory<T> factory = new ChannelFactory<T>(binding, address); return factory.CreateChannel(); } #endregion #region 创建传输协议 /// <summary> /// 创建传输协议 /// </summary> /// <param name="binding">传输协议名称</param> /// <returns></returns> private static Binding CreateBinding(string binding) { Binding bindinginstance = null; if (binding.ToLower() == "basichttpbinding") { BasicHttpBinding ws = new BasicHttpBinding(); ws.MaxBufferSize = 2147483647; ws.MaxBufferPoolSize = 2147483647; ws.MaxReceivedMessageSize = 2147483647; ws.ReaderQuotas.MaxStringContentLength = 2147483647; ws.CloseTimeout = new TimeSpan(0, 10, 0); ws.OpenTimeout = new TimeSpan(0, 10, 0); ws.ReceiveTimeout = new TimeSpan(0, 10, 0); ws.SendTimeout = new TimeSpan(0, 10, 0); bindinginstance = ws; } else if (binding.ToLower() == "netnamedpipebinding") { NetNamedPipeBinding ws = new NetNamedPipeBinding(); ws.MaxReceivedMessageSize = 65535000; bindinginstance = ws; } else if (binding.ToLower() == "netpeertcpbinding") { NetPeerTcpBinding ws = new NetPeerTcpBinding(); ws.MaxReceivedMessageSize = 65535000; bindinginstance = ws; } else if (binding.ToLower() == "nettcpbinding") { NetTcpBinding ws = new NetTcpBinding(); ws.MaxReceivedMessageSize = 65535000; ws.Security.Mode = SecurityMode.None; bindinginstance = ws; } else if (binding.ToLower() == "wsdualhttpbinding") { WSDualHttpBinding ws = new WSDualHttpBinding(); ws.MaxReceivedMessageSize = 65535000; bindinginstance = ws; } else if (binding.ToLower() == "webhttpbinding") { //WebHttpBinding ws = new WebHttpBinding(); //ws.MaxReceivedMessageSize = 65535000; //bindinginstance = ws; } else if (binding.ToLower() == "wsfederationhttpbinding") { WSFederationHttpBinding ws = new WSFederationHttpBinding(); ws.MaxReceivedMessageSize = 65535000; bindinginstance = ws; } else if (binding.ToLower() == "wshttpbinding") { WSHttpBinding ws = new WSHttpBinding(SecurityMode.None); ws.MaxReceivedMessageSize = 65535000; ws.Security.Message.ClientCredentialType = System.ServiceModel.MessageCredentialType.Windows; ws.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Windows; bindinginstance = ws; } return bindinginstance; } #endregion }
IWCFserver 是通过
svcutil.exe http://localhost:8034/WCFserver.svc?wsdl
IWCFserver dpser = InvokeContext.CreateWCFServiceByURL<IWCFserver>(Public.getXmlElementValue("LocalDpPathologySliceServ"), "basicHttpBinding");
